The COMP16 can be hooked to another processor, such as the
EQ3B or TubePre in a live or studio environment. Please note that
a microphone can not be plugged directly into the COMP16. The
microphone has to be preamplified first. The TubePre would be a
perfect preamp in front of the COMP16. We do recommend that
whenever possible, balanced cables be used. Examples of
balanced cables would be XLR or TRS (Tip – Ring – Sleeve). A
balanced cable is preferred because it generally has a greater level
of noise rejection. In other words it is less susceptible to outside
interference.
Use with a Console/Mixer Insert
The COMP16 can be connected to an insert point on a console
(mixer) by using a TRS Y-cable. This cable is Y-shaped, has a
single TRS ¼” jack on one end and two ¼” TS (Tips-Sleeve) jacks
on the other end. The single end will look like a stereo ¼”
connector jack. This end of the cable plugs into the insert jack on
the mixer channel. The other ends of the cable plug into the input
and output of the EQ3B. If the EQ3B does not work immediately,
you may want to try changing the jacks that are plugged into the
input and output of the unit.
